摘要： A powertrain for an electric vehicle includes: a motor that generates torque, a motor controller that controls the motor; a two-stage speed reducer connected to the motor and having a synchronizer movable to a neural position when the electric vehicle is parked; a pair of drive wheels connected to the two-stage speed reducer through a differential gear; a pair of electric parking brakes (EPBs) that locks or unlocks the pair of drive wheels, respectively, and a vehicle controller that controls the pair of EPBs. The synchronizer moves to the neutral position to prevent the torque of the motor from being delivered to the drive wheels.

摘要： A method for controlling a line pressure of a hybrid vehicle includes applying, by a controller, a set current corresponding to a target pressure to a first solenoid valve controlling the line pressure, driving, by the controller, a second solenoid valve to open an engine clutch after the applying step, comparing, by the controller, a difference value between a real pressure of the engine clutch sensed by a pressure sensor and the target pressure with a preset pressure after the driving step, and as a result of performing the comparing step, if the difference value is equal to or greater than the preset pressure, controlling, by the controller, an increase of a revolution per minute (RPM) speed of the electric oil pump and an increase of a pressure of the first solenoid valve to be alternately generated.
